The BDD PWM DC Motor Speed Controller is a high-performance DC motor driver designed for precision speed regulation via pulse-width modulation (PWM). Operating in a wide voltage range of 6V to 90V DC, this controller supports up to 10A continuous current (15A peak), making it ideal for medium-to-high power DC motors in industrial automation, robotics, or smart control systems.
It features voltage-based speed control (0-5V input), which enables direct integration with PLC systems, microcontrollers (MCUs), or single-chip microcomputers, allowing seamless automated speed management.
Key Features:
- Wide Operating Voltage Range:
DC 6V to 90V, ideal for various industrial and hobbyist DC motors. - High Current Handling:
Supports 10A continuous, 15A peak, with 0.01-1000W control power capability. - Precise Speed Control:
PWM signal duty cycle adjustable from 0% to 100% at 15kHz frequency for smooth motor speed adjustment. - External 0-5V Control Signal:
Accepts external analog voltage input (from PLC, MCU, etc.) to directly modulate motor speed. - Protection Features:
Reverse power connection protection
Over-voltage protection on control input
Built-in 20A fast-blow ceramic fuse for safety - Low Power Standby:
<5mA quiescent current when idle.
Specifications:
- Working Voltage: DC 6V-90V
- PWM Duty Cycle: 0%-100%
- PWM Frequency: 15kHz
- Control Voltage Input: 0-5V
- Max Continuous Current: 10A (15A peak)
- Max Power Output: 1000W (reduce current for continuous use)
- Fuse: 20A Ceramic (replaceable)
